The most common types of magnesium used in supplements include: 1  magnesium oxide, which can contain high levels of magnesium and is often used to treat migraines. 2  magnesium sulfate, which is an inorganic form of magnesium, and only small amounts of the supplement can be absorbed into the body. magnesium carbonate, which has slightly higher levels of magnesium and is more likely to cause gastrointestinal upset. magnesium chloride, which is easily absorbed into the body. magnesium citrate, of which large amounts can be absorbed into the body; it is often used to induce bowel movements.
